IMO the 120AH capacity entry is too high, being based on the 12.8v instead of 13.6v
With the capacity too high, when it gets down to say 30% in its mind, you will be lower than that. I don't know how low you would ever go so that would put you "too low".
I see the video shows how you can set "alarms". I don't know how you get the alarm if you are not watching the cell phone or what you do there.
I would use 113AH as mentioned to be on the safe side. I know the BMS will shut it down at 10v, but then you lose all 12v, which might be a problem or not until you get it going again. I guess you could set the alarm for before it got that low. Combined with using a lower AH capacity like 113AH , that should keep you in the clear?
